IMPROVEMENT IN CLOTH-FINISHING MACHINES.

Specification forming part of Letters Patent N0. 185,587, dated December19, 1876; application filed October 3, 1876.

To all whom it may concern Be it known that I, JAMEs HARPER SMITH, ofRaritan, in the county of Somerset and State of New Jersey, haveinvented certain new and useful Improvements in Cloth-FinishingMachines; and that the following is a full, clear, and exact descriptionof the construction and operation of the same, reference being had tothe accompanying drawings, making a part of this specification, inwhich- Figure 1 represents a perspective view of the machine. Fig.2represents a longitudinal vertical section of the same. Fig.3 representsa vertical section through the nap-raising brush, the pattern-cylinder,and its bearing. Fig. 4 represents a transverse section through thepattern-cylinder bearing. Fig. 5 represents the same in perspective.Fig. 6 repre sents in perspective, and Fig. 7 represents in transversesection, a modification of the bearing used to support thepattern-cylinder.

Similar letters of reference, where they occur, denote like parts of themachine in all the figures.

My invention consists in novel means used in connection with a hollowcylindrical revolving pattern, by which the nap of cloth can be raisedaccording to designs previously cut out of the pattern, said meansconsisting in a revolving brush operating in the interior of thecylindrical pattern, upon a concave surface formed by the cloth; and ina circular or semicircular stationary bearing to support and guide thecylindrical pattern, said bearing being slotted to permit the revolvingbrush to operate upon the cloth. It also consists in an endless elasticbelt or apron, that can be adjusted so as to regulate the pressure ofthe .cloth against the perforated cylindrical pat tern, as will behereinafter more fully described.

To enable others skilled in the art to make and use my invention,l willproceed to describe the same with reference to the drawlugs.

lhe frame A is provided with suitable journals for the shafts of thecylinders B B that carry the endless elastic belt or apron 0, said beltpassing under a tension-roller, E the shaft of which passes throughjournals a, that can be depressed by screws (a, so as to regulate thepressure of the cloth against the perforated pattern-cylinder D. Thiscylinder is made preferably of thin brass, with any desiredconfiguration cut out, forming openings, through which the revolvingbrush E can act upon the nap of the cloth and raise it above the surfaceof the cloth that is protected by the unremoved parts of thepattern-cylinder D. This cylinder is kept down upon the cloth by acircular or semicircular stationary hearing, F, fastened to the frame Aat each end. The bearing F has an opening or slot, f, extending nearlyits whole length for the bristles of the brush E to pass through andcome in contact with the pattern-cylinder or the cloth through itsperforations. The metal on each side of the opening f is formed with athin edge to bring the pattern-cylinder and the brush in close contactwithin the opening f. The revolving brush E, being located within thepattern-cylinder, acts upon the cloth, while itis held in a concave formfor a longer period of time than if it were passing over a convex form,and a brush made out of bristles can then be used to better advantage,and produce much finer results than could be given by a metalliccarding-roller acting upon a convex surface.

The shaft of the revol ing brush E passes through adjustable bearings c,to allow for the wear ofthe bristles and regulate its operation.

At the fore end of the machine a revolving brush, G, is located, tosmooth the cloth and remove any wrinkles that may be upon it beforereaching the hollow patterncylinder.

Motion is communicated to the revolving parts from the shaft of thebrush E. This shaft, carrying a pulley, (l, transmits its motion, bymeans of a cross-belt, to the pulley h upon the counter-shaft H. Thisshaft carries a pulley, h, that in its turn transmits its motion, bymeans of a cross-belt, to the pulley 1) upon the shaft of the cylinder13 that ad vances the elastic belt U, and with it the cloth, the latterbeing brought under the patterncylinder by friction with the elasticbelt. The brush G is revolved by a belt passing over a pulley, g,mounted upon the shaft of the brush E, by which the cloth I is smoothedafter it has been dampened, and before reaching the pattern-cylinder.

Having thus described my invention, what I claim is- 1. In acloth-finishing machine, a semicircular stationary bearing, having anopening or slot, f, formed with thin edges, in combination with arevolving brush inclosed within a cylindrical pattern, substantially asand for the purpose described.

2. A revolving brush, E, inclosed in a revolving cylindrical pattern,and operating upon its concave surface, in combination with a stationaryslotted cylinder, substantially as described.

3. A revolving brush, G, for smoothing cloth previous to raising itsnap, according to certain designs, in combination with pattern-cylinderD and an endless elastic apron, (l, and a revolving brush, E, adapted tooperate upon a concave surface of the cloth, substantially as set forth.

4. The adjustable roller B, to regulate the tension or pressure of theelastic apron G, in combination with a pattern-roller inclosing arevolving brush, substantially as and for the purpose described.

5. In combination with a revolving brush, E, operating upon the concavesurface of a hollow pattern-cylinder, supported by a cylindrical orsemi-cylindrical stationary bearing, F, and an elastic apron supportingthe cloth to be operated upon, the adjustable bearings e of said brushto regulate the operation, substantially as described.
